solmaris [256]

Answer:

y = 0.5,  1,  1.5,  2

Step-by-step explanation:

x is twice as much as y, so when you multiply the input for y by 2, it should get the value of x. Example: if y is 1, then x is 2, because 1*2 = 2

if there is 2/3 of a bag of jelly beans, and Danny ate 1/4 of the bag last night, what fraction of the bag is left?
scoundrel [369]
2/3-1/4=5/12
You could make the denominators common by finding the GCF

The GCF of 4 and 3 is 12

This means that 8/12-3/12 which would give you 5/12.

On a very hot summer day, 5% of the production employees at Midwest Auto Works are absent from work. The production employees ar
olga2289 [7]

Answer:

1.05% probability of randomly selecting 10 production employees on a hot summer day and finding that three of them are absent

Step-by-step explanation:

For each employee, there are only two possible outcomes. Either they are absent, or they are not. The probability of an employee being absent is independent of other employees. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

5% of the production employees at Midwest Auto Works are absent from work.

This means that p = 0.05

What is the probability of randomly selecting 10 production employees on a hot summer day and finding that three of them are absent

This is P(X = 3) when n = 10.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 3) = C_{10,3}.(0.05)^{3}.(0.95)^{7} = 0.0105

1.05% probability of randomly selecting 10 production employees on a hot summer day and finding that three of them are absent

Please help solve this question. Thanks

Answer:

A = -y^2 + 18

y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)


Step-by-step explanation:

Given:

P = 2 ( l + w)

x = length and y = width

P = 2 (x + y)

36/2 = x + y

x + y = 18

x = 18 - y


<u>Area:</u>

A = x * y

A = (18 - y) * y

A = 18y - y^2

Using quadratic formula (<u>solve for y</u>):

y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)
